不良率が低く、銅張りガラエポの生産性は向上される。According to the method for producing a prepreg for a laminated plate of the present invention comprising the above steps, the excessive epoxy resin adhered portion to the glass cloth due to the fluffing of the glass cloth is crushed,
Since the prepreg is smoothed and the plate thickness of the prepreg is made uniform, the copper-clad glass epoxy that is formed by using this prepreg has a low wrinkle defect rate and the productivity of the copper-clad glass epoxy is improved.

ラをそれぞれ示す。EXAMPLE In the present invention, glass cloth is impregnated with an epoxy resin and dried after the glass epoxy prepreg is manufactured, and then compressed by a heated roll.
By the compression with the heating roll, the excessive epoxy resin adhered portion due to the fluffing of the glass cloth is crushed to smooth it and make the plate thickness uniform. As the heating roll, one whose surface is heated to about 80 ° C. with warm water or a thermal catalyst is used, and the prepreg is sandwiched between a pair of vertically facing heating rolls. FIG. 1 is a schematic diagram of an example of the prepreg manufacturing apparatus for carrying out the present invention. In this figure, a continuous glass cloth continuous sheet 1 from a glass cloth supply source (not shown) passes through a kiss bath 2 for pre-impregnation of an epoxy resin, a timing bath 3 for main impregnation, and a squeeze bath 4 for pushing out excess resin. Then, an appropriate amount of epoxy resin is applied, passed through the drying tower 5 to be dried, and then passed through a pair of compression heating rolls 6 facing each other vertically. In the figure, 7 is a drying tower 5.
Reference numeral 8 denotes a guide roller for guiding the glass cloth sheet therein, and reference numeral 8 denotes a guide roller forming a loop before and after the compression heating roll 6.
